all parts the main body will not show anymore. I did 2 uninstall and installs with same results.
Clean uninstall and Re-install will work.

Well, it looks like the part body is hidden. Did you check under the solid bodies folder to see if the body is hidden?
Also check you scene settings to make sure your sceen floor isn't flipped and therefore concealing your model. The presence of the drop-shadow is an indication of that situation.
You can also just open one of the sample models that comes with Solidworks 2020 and see if they display the same way.
%public%\public documents\Solidworks\Solidworks 2020\samples
Assuming you did and they don't, this seems to be a display pipeline issue.
I'd launch Solidworks from Solidworks Rx using the Software OpenGL settings and see if the model shows up then. If that's the case then you've got a video driver issue. If you're running an older card, then you'll want to install the Nvidia Enterprise drivers for your GPU.
Let us know how it turns out.
